Re: Adding to Cluster

HiAs far as I am aware you can add any node to any cluster however:1: you should not mix sas with sata with VSA2: you should think about potential performance issues if mixing different h/w3: if the node you have in has MORE capacity than any existing node in the cluster then you WILL NOT be able to use the "extra" capacity of that node. You will be stuck at the smaller size - this is called stranded capacity.Note - if you add a smaller node into a cluster then it will go to the smaller size !!!! You have NO choice in that!You need 4 nodes (min) in a cluster to do network raid5. I think from your post you will only have three ??Mark...

Re: Adding to Cluster

4 nodes is the requirement for Network RAID 5 (3 data and 1 parity).

I don't think you'll double your space really if you moved to RAID 5. The benefit is in the snapshot area. Your workload should be kept in mind as well, you don't want to use NW RAID5 for highly transactional workloads.
